In the 1990s and 2000s, Lake Michigan experienced large [[algae blooms]], which can threaten aquatic life. Responding to this problem, in 2009 the city became an "Innovating City" in the [[United Nations Global Compact|Global Compact]] Cities Program. The Milwaukee Water Council was also formed in 2009.<ref>{{cite web|url=https://thewatercouncil.com/wp-content/uploads/Our_History_Web_4-19-19.pdf|title=Our History|publisher=Milwaukee Water Council|website=Thewatercouncil.com}}</ref> Its objectives were to "better understand the processes related to freshwater systems dynamics" and to develop "a policy and management program aimed at balancing the protection and utilization of freshwater". The strategy used the [[Circles of Sustainability]] method. Instead of treating the water quality problem as a single environmental issue, the Water Council draws on the Circles method to analyze the interconnection among ecological, economic, political and cultural factors.<ref>{{usurped|1=[https://web.archive.org/web/20170702212539/http://citiesprogramme.com/aboutus/our-approach/circles-of-sustainability Circles of Sustainability]}}.
